Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582710, here are decompositions:

31 + 31582679 = 31582710
37 + 31582673 = 31582710
43 + 31582667 = 31582710
79 + 31582631 = 31582710
83 + 31582627 = 31582710
97 + 31582613 = 31582710
101 + 31582609 = 31582710
109 + 31582601 = 31582710

Showing the first eight; more decompositions exist.
